Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly catch uninitialized-variable defects via static analysis and code review while the control encompasses many additional development controls.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect uninitialized-variable bugs, but the control is broader.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates practices that reduce uninitialized-variable defects.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify initialization rules, but the control itself does not directly address the weakness.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture and engineering principles include defensive coding practices that prevent use of uninitialized memory or objects.

A.8.28 Secure coding partial match
prevents

Secure coding explicitly requires variable initialization and static-analysis checks.
